Description

Technical Field

[0001] The utility model relates to the technical field of LED electronic display, in particular to an LED module of an electronic circuit display screen. Background Art

[0002] LED module circuit board is a metal-based copper-clad board with good heat dissipation function. Generally, a single-sided board consists of a three-layer structure, namely the circuit layer (copper foil), the insulation layer and the metal base layer. It is commonly found in LED lighting products and has two sides. The white side is for welding LED pins, and the other side is the original color of aluminum. Generally, thermal conductive slurry is applied to contact the thermal conductive part.

[0003] The current LED module circuit board is generally a whole large board when used on electronic screens. Each LED lamp bead is directly soldered on the circuit board. The heat generated by the light-emitting chips packaged inside each LED lamp bead during operation is accumulated to a great extent, which requires a high heat dissipation effect of the circuit board, and will interfere with the heat generated by the various electronic components on the circuit board during operation.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A LED module for an electronic circuit display screen, comprising a circuit board module, wherein the number of the circuit board modules is several, and a lamp bead integrated substrate is fixedly installed on the front side surface of the circuit board module, and an LED module unit is embedded on the front side surface of the lamp bead integrated substrate. The number of the LED module units is several, and the lamp bead integrated substrate comprises a substrate body, a docking card slot is provided on one side of the substrate body, and a No. 1 docking card strip is fixedly installed on the other side of the substrate body.

[0008] Furthermore, the lamp bead integrated substrate includes a substrate body, a front surface of the substrate body is arranged with a plurality of lamp bead card slots in a rectangular array, conductive metal sheets are embedded in the upper and lower surfaces of the lamp bead card slots, and locking buckle grooves are provided on the two side surfaces of the lamp bead card slots.

[0009] Furthermore, the LED module unit includes a substrate, a plug-in block is fixedly installed on the rear surface of the substrate, an LED lamp bead is embedded in the front surface of the substrate, conductive springs are embedded in the upper and lower surfaces of the plug-in block, locking springs are fixedly installed on the two side surfaces of the plug-in block, locking buckles are fixedly installed on the outer surface of the locking spring, spring movable grooves are opened on the two side surfaces of the substrate, and the front ends of the locking springs extend into the spring movable grooves.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. A certain isolation is formed between the circuit board module and the LED module unit through the substrate body, so as to reduce the interference between the heat generated by the light emission of the LED chip of the LED module unit and the heat generated during the operation of the circuit board module. At the same time, a fan independent of the substrate body is used to fill the air into the air duct, and the air is filled into the ventilation chamber through the No. 2 docking card strip that is mutually engaged with the docking card slot to cool each LED module unit. A relatively independent lamp bead card slot that provides installation space for each LED module unit is used to provide a relatively uniform cooling effect for each LED module unit. Part of the airflow circulating in the ventilation chamber will be discharged from the active groove of the spring through the cooling air duct, so that the airflow can be closer to the chip structure of the LED lamp bead, thereby improving the heat dissipation effect.

[0015] 2. When an LED lamp bead on the LED display lamp bead module board fails and cannot be used normally, the LED module unit where the faulty LED lamp bead is located can be directly pulled out from the front side of the substrate body and replaced. While facilitating maintenance, it also avoids the problem of a single LED lamp bead in the LED display lamp bead module board where traditional LED lamp beads are integrated and packaged together, affecting the normal use of the entire module board, thereby improving the overall service life of the module board.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 6In an embodiment of the utility model, an LED module of an electronic circuit display screen includes a circuit board module 1, a lamp bead integrated substrate 2 is fixedly installed on the front surface of the circuit board module 1, an LED module unit 3 is embedded on the front surface of the lamp bead integrated substrate 2, and the number of LED module units 3 is several. A ventilation chamber 205 which is interconnected with each lamp bead card slot 202 is opened on the rear surface of the substrate body 201, a docking card slot 206 is opened on one side of the substrate body 201, a second docking card strip 208 is clamped at the docking card slot 206, a duct 210 is fixedly installed on one side of the second docking card strip 208, and a fan 211 is fixedly installed on the upper end of the duct 210.

[0026] Specifically, a certain isolation is formed between the circuit board module 1 and the LED module unit 3 through the substrate main body 201, so as to reduce the interference between the heat generated by the light emission of the LED chip of the LED module unit 3 and the heat generated during the operation of the circuit board module 1. At the same time, a fan 211 independent of the substrate main body 201 is used to fill the air into the air duct 210, and the air is filled into the ventilation chamber 205 through the No. 2 docking card strip 208 that is mutually engaged with the docking card slot 206, so as to cool each LED module unit 3. A relatively independent lamp bead card slot 202 that provides an installation space for each LED module unit 3 is used to provide each LED module unit 3 with a relatively uniform cooling effect.

[0027] Embodiment 1

[0028] like Figure 1-4 As shown, in this embodiment, the circuit board module 1 includes a mainboard 101, threaded sleeves 102 are fixedly installed at the four corners of the mainboard 101, splicing slots 103 are provided at two adjacent edges of the mainboard 101, and splicing card strips 104 are fixedly installed at the other two edges of the mainboard 101; a No. 1 docking card strip 207 is fixedly installed on the other side of the substrate body 201, and connecting channels 209 are provided in both sides of the No. 1 docking card strip 207 and the No. 2 docking card strip 208, and the connecting channel 209 is connected to the ventilation chamber 205; the substrate body 201 is fixedly installed on the front surface of the mainboard 101, and various electronic components are integrated and installed on the rear surface of the mainboard 101 and the circuit is etched.

[0029] In this embodiment, a suitable number of circuit board modules 1 can be selected according to the size of the screen installation port of the device using the electronic circuit display screen as needed. The splicing card strips 104 and the splicing card slots 103 are used to mutually snap together to assemble the various main boards 101 to form a circuit board module 1 assembly of a suitable size. The main board 101 is also modularly designed to expand the applicable scope of the overall structure. At the same time, when splicing the various main boards 101, the No. 1 docking card strip 207 and the docking card slot 206 are also snapped together, and the ventilation chambers 205 inside the various substrate bodies 201 are interconnected by using the connecting channel 209. When the wind passes through the various ventilation chambers 205, it can simultaneously perform heat dissipation and cooling work on the circuit board module 1 and the LED module unit 3, thereby improving the cooling effect.

[0030] like Figure 6 As shown, in this embodiment, cooling air ducts 308 are opened inside both sides of the insert block 302 .

[0031] During specific implementation, part of the airflow flowing in the ventilation chamber 205 will be discharged from the spring movable groove 306 through the cooling air duct 308, so that the airflow can be closer to the chip structure of the LED lamp bead 307, thereby improving the heat dissipation effect.

[0032] Embodiment 2

[0033] On the basis of the first embodiment, in order to compensate for the problem in the single LED module unit 3 in the first embodiment, a specific method of performing maintenance work is provided.

[0034] like Figure 1 , 3 5-6, in this embodiment, the lamp bead integrated substrate 2 includes a substrate body 201, and a plurality of lamp bead card slots 202 are arranged in a rectangular array on the front surface of the substrate body 201, and conductive metal sheets 203 are embedded in the upper and lower surfaces of the lamp bead card slots 202, and locking buckle grooves 204 are provided on the two sides of the lamp bead card slots 202; the LED module unit 3 includes a substrate 301, and an insert block 302 is fixedly installed on the rear surface of the substrate 301, and an LED lamp bead 307 is embedded in the front surface of the substrate 301, and the insert block 303 is provided on the front surface of the substrate 301. Conductive spring pieces 303 are embedded in the upper and lower surfaces of 02, locking spring pieces 304 are fixedly installed on the two side surfaces of the plug block 302, and locking buckles 305 are fixedly installed on the outer surface of the locking spring pieces 304. Spring piece movable grooves 306 are opened on the two side surfaces of the base sheet 301, and the front end of the locking spring piece 304 is inserted into the spring piece movable groove 306; the plug block 302 is inserted into the lamp bead card slot 202, the conductive spring piece 303 is slidably connected with the conductive metal sheet 203, and the locking spring piece 304, the locking buckle 305 and the locking buckle groove 204 are buckled with each other.

[0035] In specific implementation, the LED display screen lamp bead module board in which the original LED lamp beads 307 are integrated and connected in series is optimized and designed into an LED module unit 3 in which each LED lamp bead 307 exists independently, and is inserted into the lamp bead card slot 202 through the plug block 302, and is installed on the front surface of the substrate body 201 in an independent posture to form a new type of LED display screen lamp bead module board in which each LED lamp bead 307 is relatively independent. When an LED lamp bead 307 on the LED display screen lamp bead module board fails and cannot be used normally, the LED module unit 3 where the failed LED lamp bead 307 is located can be directly unplugged from the front side of the substrate body 201 and replaced, which is convenient for maintenance and avoids the traditional problem of each LED lamp bead 307 being integrated and sealed. A problem occurs in a single LED lamp bead 307 in the assembled LED display lamp bead module board, which affects the normal use of the entire module board. In order to improve the overall service life of the module board, when the plug block 302 is inserted into the lamp bead card slot 202, the conductive spring 303 and the conductive metal sheet 203 slide and contact each other to connect the power channel between the lamp bead integrated substrate 2 and the LED module unit 3. After the plug block 302 is inserted into the lamp bead card slot 202, the locking spring 304 and the locking buckle 305 are buckled into the locking buckle groove 204 to lock the connection between the lamp bead integrated substrate 2 and the LED module unit 3. When a single LED module unit 3 is removed, the locking spring 304 can be toggled from the spring active groove 306 to achieve unlocking.
